A license plate recognition system is an automatic system that is able to recognize a license plate number, extracted from an image device. Such system is useful in many fields and places: parking lots, private and public entrances, border control, theft and vandalism control. In our paper we designed such a system. First we separated each digit from the license plate using image processing too...

Automatic Number Plate Recognition (ANPR) is a mass surveillance system that captures the image of vehicles and recognizes their license number. ANPR can be assisted in the revealing of stolen vehicles. The recognition of stolen vehicles can be done in an efficient manner by using the ANPR systems located in the highways. ANPR systems are very useful to the law enforcement agencies as the need ...

In this paper, we present a new design flow for robust license plate localization and recognition. The algorithm consists of three stages: 1) license plate localization; 2) character segmentation; and 3) feature extraction and character recognition. The algorithm uses Mexican hat operator for edge detection and Euler number of a binary image for identifying the license plate region. A pre-proce...

Abstract: In our examination, a powerful algorithm for plate recognition which is able to recognize plates having different dimensions in unaccustomed and complicated backgrounds.License plate detection is first step in ANPR systems. The paper defines an algorithm to detect license plate.The plate is detected based on its edge density features. Integral edge image is calculated and then edge de...

Here we describe a project that deals with license plate location in raster images. The algorithm takes a raster image as input, and yields the position of a plate in the image. After the position is determined, the algorithm can determine the locations of the license plate characters, which could be easily combined with an OCR algorithm to convert the license plate number into an ASCII string.

This paper presents a wavelet transform based method for extracting license plates from cluttered images. The proposed system consists of three major stages. First, a wavelet transform based method is used for extracting important contrast features as guides to search for desired license plates. Then, finding a reference line in HL subimage plays an important role to locate the desired license ...

This work aims to investigate the use of a drone-based system to recognize license plates of vehicles in a parking lot. Many parking lots contain surveillance cameras mounted on walls or light towers for indoor and outdoor lots respectively. Parked vehicles are commonly monitored by law enforcement agents by driving around the parking lot to identify license plates with an onboard camera or a h...
